RAILROAD-TIE.

Specification of Letters Patent.

To all whom, it may concern.-

Be itknown that I, HERBERT E. PERGIVAL, a citizen of the United States,and a resident of Galveston, in the county of Galveston and State ofTexas, have invented a new and useful Improvement in Railroad-Ties, ofwhich the followingisafull, clear, and exactdescription, reference beinghad to the accompanying drawings, forming a part of this specification,in explaining its nature.

My invention relates to an improvementin railroad-ties and to that kindof tie known as a cement tie, or, more specifically, one made ofconcrete.

The essential object of my invention is to make a tie which will notbecome centerbound, also the construction of improved means by which therails may be secured to the cement tie, which means include a lookingdevice by which the rails may be secured to the tie without the directuse of spikes, bolts, or means of a similar nature having a directconnection with the tie.

The formation of my improved tie, as also the means by which the railsmay be secured to it, may best be seen and understood by reference tothe drawings, in which- Figure 1 shows the improved tie and lockingdevice inside elevation. Fig. 2 shows the same in plan. Fig. 3 shows inplan a section on the line 3 3 of Fig. 1. Fig. 4: shows a section on theline a +1 of Fig. 1. Fig. 5 shows a section on the line 5 5 of Fig. 1.Fig. 6 shows in plan the different parts comprising the locking device.Fig. 7 shows in plan a slight modification of the locking device, towhich reference will hereinafter be made.

Referring to the drawings, A represents the improved tie, B the rail,and O the locking device for securing the rail to the tie, a descriptionof which device will hereinafter be made.

Referring to the construction of the tie, the head (a of the tie is maderelatively broad, so as to present a stable base for the rails, and ispreferably made also with a flat top surface. The sides of the body ofthe tie converge or incline inwardly. At the ends of the tie where therails come the inclination of the portions (1/ a of its sides is not toopronounced or with such degree of convergence that the tie may haverelatively broad bottom edge portions (4 (4 These portions arepreferably made relatively rounding and thus broad in order that theends of the tie when weight is applied may Withstand the pressure of thesame without undue sinkage. Passing in from the ends of the tie theconvergence of its body sides rapidly increases until all along thecenter of the tie the convergence of its side portions (0* a slopinginwardly from the very top of the tie, is such that they meet to form anarrow bottom edged, which presentsan almost sharp or cutting edge orsurface to the filling or ballast in which the tie is laid. Thisformation of the tie along the center as contrasted with its endportions can best be seen in Fig. 5, where it is shown that the tie whenmade with a flat top surface is substantially triangular incross-section at its center. Moreover, it is to this peculiar shape ofthe tie along its center to prevent the center-binding that theimprovement in the tie more essentially pertains. The prevention ofcenter-binding is obtained not only by reason of the sharp bottom edgealong the center of the tie, which allows it to cut or sink into theballasting correspondingly as either or both ends of the tie becomedepressed by the weight to which it is subjected, but also, and perhapsmore essentially, from the fact that the. sides slope or converge fromthe very head of the tie; otherwise, though the bottom along the centerof the tie be made relatively sharp and narrow, it would be of littleavail.

\Vith reference now to the locking device O, by which the rail B issecured to the concrete tie, there are arranged upon the ends of the tiewhere the rail comes adjacent clamp members 0 0. These members are madeof metal plate, and in form they are substantially identical. Eachcomprises a top plate 0 and depending side plates 0 c, oppositelyarranged, the inwardly-bent edges of which sides conform to the shape ofand are adapted to engage with or grip the inwardly-inclined sides ofthe tie. In this connection it is to be noted that I reinforce the uppercorners of the tie where the side edges of the locking device make theirengagement with the angular reinforcements or guards a". It is also tobe noted that when these clamp members are properly arranged upon thetie there remains a space between the top plate 0 of the respectivemembers and the top surface of the tie, and these spaces are filled,preferably, with a cushion-block D, which sits into-a slight recess aformed in the top of the cement tie. The clamp members rest upon thisblock, but with the side plates 0 0* depending to engage with the tie,as just described. The clamp members 0 0 thus in conjunction with thetie can be moved longitudinally with re spect to it or to and from oneanother. On the top plate 0 of each of the respective members is formeda tongue or clip 0", punched or stamped out of the metal of the plates.These clips are oppositely arranged and are adapted when the clampmembers 0 0 are moved, or rather shoved into conjunction with each otherend to end, to engage with the respective flanges Z) 6 of the rail B,which rests upon the meeting top plates 0 of the respective members whenin conjunction.

For holding the respective clamp members thus in conjunction, holdingthe rail in place, and at the same time locking the rail to the tie inany adjusted position there are provided the fish-plates 0 Hand thetie-rod or bolt 0 These plates 0 c are made substantially alike tocorrespond in form with the side plates of the respective clamp members,against which they are placed one on one side and the other on the otherside of said members after the same have been brought into properconjunction to hold the rail. as before stated. It is to be noted alsothat the respective plates have tongues or clips 0" c punched or stampedoutof their metal, which enter into holes a 0 fOI'IIlGCl in the sideplates 0 c" of the respective clamp members, by which clips the membersare held from being drawn apart from one another. The members being thusarranged are tied together by the bolt 0, passed through the fishplates0 0 by means of holes (2 cut in them, whereby the bolt will pass betweenthe meeting ends of the clamp members and also through the cushion-blockD on the inside, the meeting edges of the clamp members being reamed outat the points 0 to form a bolthole, which is also formed through theblock. A locking-nut 0 is arranged on the end of the bolt or tie-rod,and by turning up this nut the clamp'members are not only retained insuch manner as to hold the rail, but as the nut is turned up pressurewill be exerted to draw the engaging side plates of the respectivemembers fast against the sides of the tie, by which means the clampmembers, and so the rails, become immovably locked in place without theuse of any spikes or other means having direct connection with the tie.

In Fig. 7 there is shown a slight modification in the construction oftheloeking device in the fact that the fish-plates are dispensed withand the clamp members cand a are provided with flanges c and 0,respectively, which lap by one another and through which overlappingflanges the bolt 0 is passed.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States 1. A cement tie of the characterspecified, having a broad head, inwardly-inclined sides for the bod y,the respective ends of the tie made to present a relatively broadl.)earingbase,and between the ends of the tie the body sides thereofinclining from the very head of the tie and converged to form a basepresenting a narrow cutting surface or edge.

2. A cement tie of the character specified, having a broad head,inwardly-inclined sides for the body varying in the amount of theirinclination from the ends of the tie formed with a relatively broadbearing-base toward the center thereof by the inclined body sidesbetween the ends converged to form a base presenting a narrow cuttingsurface or edge.

3. A cement tie of the character specified, having relatively broadbearing end bases, and along the middle of the tie the sides of the bodythereof inclined inward and converging to form a base presenting anarrow cutting surface or edge.

f.
